Create a tidy pond! The Ubbink aquatic plant bag with an aquatic plant in it can be placed both in the water and on the edge of the pond. The aquatic plant bag keeps the plants from spreading throughout the entire pond and also keep the soil from floating around in the pond. In addition, the soil doesn't wash away, keeping the plant healthy. If you put the aquatic plant in a pond plant bag, it will also be easier to take it out of the pond and take care of it.
